Engineer specialized in optical studies and design | French national synchrotron facility
Mar 15 2023
SOLEIL is the French national synchrotron facility, located on the Saclay Plateau near Paris. It is a multi-disciplinary instrument and research laboratory whose mission is to conduct research using synchrotron radiation, to develop cutting edge instrumentation on the beamlines, and to make these developments available to the scientific community. SOLEIL synchrotron, a unique tool for both academic research and industrial applications across a wide range of disciplines including physics, biology, chemistry etc., opened in 2008. It is used annually by thousands of researchers from France and abroad. SOLEIL is based on a synchrotron source that is state-of-the-art both in terms of brilliance and stability. This large scale facility, a partner of the Université Paris Saclay, is a “publicly owned” private company, founded by the CNRS and the CEA.
This position is with the Optics group, within the Science division.
Within the Science division, the optics group is tasked with the design and maintenance of the beamlines. The optics group develops or specify the optical components and is responsible for their metrological control, validation, deployment and maintenance. For these missions, the optics group consists of 5 research engineers and 1 engineer or technician specialized in X-ray optics and thin multilayer coating.
I.Mission
Specialized in optical study and design, the engineer’s mission is to assist the group leader in the definition and the calculation of complex optical systems for a very broad spectrum of wavelength from the infrared to the hard X-ray.
The engineer will work with strong interactions with the other group members in order to check the feasibility of the optics he or she will be led to design and the ability of the group to measure the optics within the specified tolerances. He or she will also check that said optics are mountable in the beamline by interacting with the engineers of the optics group in charge of the integration of the optics on the beamlines.
The engineer will participate in the functional definition of the optical systems with the group leader and the final users. He or she will make the necessary calculations for their optimization. He or she will write the technical specifications for the manufacture of the optics and associated mechanical supports as well as handle the project from manufacturing to installation on the beamlines.
The engineer’s participation to the group’s research focuses on the development of new components, their characterization and use in innovative systems. In this context, the engineer is tasked with developing and maintaining software for the characterization of these components on the associated beamlines.
He or she makes the optical simulations using different software available at SOLEIL such as CODE V or internally developed software like PyOptiX, Solemio and Carpem or occasionally using other publicly available software like Shadow.
When defining an optical system, he or she will assist the scientist in charge of the equipment in choosing the best compromise in order to achieve the expected performances. He or she will provide the necessary quantified elements leading to the final decisions. He or she will optimize the chosen optical solutions and compute the associated tolerances.
The engineer will prepare the calls for tender for the optics and follow the manufacturing process.
When the optics are being installed, he or she will assist the engineer in charge of the mounting of the elements and provide models for identifying misalignement sources.
He or she will maintain the documentation about the optical systems he or she is in charge of so as they are up to date with their current status using the tools provided by SOLEIL both in the common documentation (CMMS) and in the simulations files for the group (PyOptiX, SOLEMIO, CODE V)
He or she will be tasked with at wavelength metrology of optics for tender X ray optics. Thus, he or she defines the necessary measurement protocols and develops the necessary tools on the Metrology beamline available both for internal and external users
He or she will develop a personal R&D project in a frame defined with the optics group leader so as to fit with the other research programs within the group.
II.Qualification & Experience
This position is for an engineer level graduate specialized in optics with extended knowledge in X-Ray optics. A work experience of several years in the synchrotron community is necessary. A PhD in a related field would be much appreciated.
